> We have seen this issue happen with the below steps
>    1. Clear out the zookeeper
>    2. Update the storage plugin using the rest API on one of the node
>    3. Submit 10 queries concurrently
> With randomized foreman node selection, the node executing the query might not have the
updated storage plugins info. This could be causing the issue.
